Incidental Tc-99m MIBI Lung Uptake in Parathyroid Scintigraphy.

Diffuse Tc-99m MIBI uptake in the lungs during parathyroid scintigraphy is exceptional, and only a few cases have described this unusual aspect. The differential diagnostic of this funding is a challenge when interpreting the examination, since it can be a sign of serious pathology. We report the case of unexpected diffusely increased Tc-99m MIBI uptake in bilateral lung fields in a patient with left cardiac dysfunction.
